Circle diagram (rotated).

A 13-odd-limit Dekany. This creates a scale of 1 13/12 11/10 143/120 13/10 3/2 33/20 9/5 11/6 39/20 2/1, with steps of 13/12 66/65 13/12 12/11 15/13 11/10 12/11 55/54 117/110 40/39. With a stable minor seventh chord above the root, but also plenty of more spicy semiquartal harmony, this is quite interesting to play with, although the number of tiny steps is a little suboptimal for a scale of this size.
